This invention relates to machines for slicing meat and othercommodities, and has for one of its objects the provision ot a-slicing machine in which the work: support remains stationary While the slicing knife is moved transversely thereof to sever a slice from material on the work support.

' A further object is'to provide apower drive for reciprocating said slicing knife relative to the work support and simultaneous.- l'y rotating the slicing knife; r

A further object is to "provide a slicing machine which shall be of improved construction and operation.

particularly pointed out in the appended claims.

In thedrawingsr r Fig.1 is an elevation, with parts in section, showing one embodiment of the present invention; I

Fig.2 1s a top 'plan View of the machln'e shown Fig. 1 with the support for the slicin knife shown'in section; f

i 3 is a diagrammatic view showing one formofreleasable connection for the knife in element; Fig. 5 is a section of a frictiondrive forming a part of the construction illustrated in Fig. 6 is an elevation of a modified form of the invention having the motor mounted on the reciprocating support for the knife.

The numeral 10 designates a base or support havinga pedestal 11 thereon in the upper end of which a drive shaft 12 is journaled forrotation. The drive shaft12is driven by worm gearing 13 from a motor lt'mounted on the pedestal '11. A knife supporting bracket 15 is swung upon the pedestal 11 for reciprocation about the shaft 12 as an axis. The bracket 15 supports alhousing 16 in which. sprocket wheels l'i, and 19' are mounted. The sprocket wheel '17 is secured to the shaft 12, while" thefsprocket wheels 18 I and are mounted o'nishatt's 20, and 21, re spectively; journaled iii the housing 16. "The slicing knife 22 is secured to the shaft 20.

A. sprocket chain 23 is trained: over the sprocket wheels 17, 18 and I9; Itwillbe apparent that rotation of the shaft 12 willrotate the sprocket wheel 18 and knits thereon irrespective ofthe position of the housing 16 upon lts pivotal support12. The'housin-g 1-6 is oscillated upon its support 12 to move the knife 22 past the work support for severmg slices by 'meansof a-link 24c journaied on a crank pin 25' on the sprocket, wheel 19 and having its opposite'endpivoted upon a'pin 26 mounted in fixed position on, thepedestal 1-1',- 'The bracket15 maybe provided with slot 27to permit "oscillation of thebracket wlthoutinterference by the pin 26. Rotation of the sprocket wheel 19 will operate to shift the bracket 15 housing 'll'6 ba-ck and forth between thefulllineand broken line positions shown in Fig. 1,"thus moving the sllc'ing knife 22 past the worksupp'ort si multaneously with the rotation of the slicing knife :thus severing slices from the material held by the work support.

The work holder comprises "a supporting plate 28"mounted to slide on the base '10" in a direction normal to thecuttingjp'l'ane of the knife'22and has a clamp 29 for securing work'thereonf The-work holder 28 is fed toward the slicing knife byi t'threaded screw operated by a ratchet wheei'30 in a well-known manner; The-ratchetwheel is actuated y a p l 31 carried by'an arm 32 which isjconn-ected by a link33 with a; pivot pin 34 on the bracket 15. The amount of rotation of the r-atchetwheelis Fcontrolled by a cam 85 which may be adjusted by a lever 36 and operating rod 37; r

It is sometimes desirable to rotate the slicingknife without oscillating the supporting bracket therefor, as, for instance, for the purpose of sharpening the knife. One arrangement for producing this operation is illustrated"diagrammatically in Fig. 3 in which the link 24 is provided with a long-iback and forth longitudinally without shift ing the housing 16. A similar result may be obtained by mounting the crank pin 25 so as to be operated by a frictional drive, as indicated in Figs. 4 and 5. In this case the crank pin 25is secured to a friction disc 41 having frictional contact with the sprocket wheel 19, the parts being held inengagement by a spring 42. With this construction the housing- 16 may be locked against reciprocation and the sprocket 19 will be rotated relative to the crank pin 25, whichwill remain stationary. The sprocket 19 in Figs. 3 and 4 may be driven from a motor mounted on the casing 16 as in the form of the inven tion shown in Fig. 6, or from a stationary support as in Figs. 1 and 2. I

In the modification shown in Fig. 6, the motor 45 is mounted on a bracket 46 carried by the reciprocating knife support 47. The knife 48 is mounted on a shaft 49 driven by a sprocket wheel 50 over which the s rocket chain 51 travels. A sprocket whee 52 is provided with a crank pin and link connection,.not shown in the drawings, but similar to that of Fig. 1 for oscillating'the knife 7 support 47. The knife support 47 shown in Fig. 6 may also be oscillated by means of the crank and pitman connection shown in Fig. 3 if desired, instead of by a straight link as shown in Fig. 1. The sprocket chain -51 is driven by a sprocket 53 journaled at the end of the support 47 opposite the knife 48 and connected with a driving disc .54 which has a frictional driving connection with a drive pulley 55 on the motor .45. In this arrangement the motor 45 is utilized ,for counterbalancing the weight of the knife 48. The support 47 is frame member 11:.
